Overpriced, but very nice.
First of all, I'd give it 5 stars except for the price. It’s sad to see they’re getting for this switch. I design low volume, custom electronics so I understand that an item like this isn’t going be produced in the millions and tooling charges need to be recouped. But man, they are gouging us for this.
Ok, enough venting… I bought the CU-1 for my SK1-73. Yes, the SK1 IS NOT designed to accept this switch (mechanically speaking), but I really detest using the Leslie buttons on the SK1. After considering my options for mounting this, I decided to modify the SK1’s chassis to accept the CU-1. I got a $17 threaded rivet kit from Harbor Freight which comes with the tool and a selection of threaded rivets. I positioned the CU-1, marked out the holes, drilled and installed threaded aluminum rivets to accept 1” long 8-32 machine screws for a rock solid mount. Each end plate of the SK1 comes off with three screws so I could insure that no aluminum shavings from the drilling would be inside the keyboard. The Hammond gig bag has enough room to allow the CU-1 to be left on the keyboard. This isn’t an option many will consider, but it got me what I wanted. It’s not perfect since you’re putting in the inserts close to the edge, which has a radius. I considered forming the rivets around the radius, but just mounted the switch and got on with life. I took pictures and video of the operation if anyone wants to email Chad Klink.
I just played a rehearsal with the CU-1 attached and all I can say is “Ahhhhhh. That’s much better”. Using the included spacer and mounting the CU-1 as far left as possible puts it just at the end of the keys and feels very natural for me. The detent of the switch is firm and crisp. Of course, it looks authentic. The SK1’s setup allows you to select the CU-1 as your foot switch input, so it works right away. While I can complain about the price, I must say that I enjoyed playing more with this switch in place. It just feels right.
